following is a specification', taken in vconnota-- .tion with .the -accompanying drawings, which form apart of the same. f

This invention relates to loose leaf binders and more particularly to sectional posts or pillars for such 4binders and means 4for readily `attaching" and detachiug the different sections. y It-also relates to `supports or'disks which may form a part of the posts or pillars and which may be used to support a portion of the contents of the loose leafbinders an l also', if desired, form a rear index. In theaccompanying drawings showing illustrative embodiments of this invention, and' in which the: samev -reference numerals refer to simi-lar .parts in the several figures, Figure 1 is a longitudinal vert-ical section of aloose:` leaf binder equipped' with my'invention. Fig. 2 is a side elevation vof two of thesections of thepost in position to be as-y sembled. Fig.' 3 `is a plan view of a support or disk which. may be .used with a post or pillar of a loose leaf binder. Fig. 4 is a side'elevation of the support orl disk shown in Fig. l3. Fi -5 is a fragmentary plan,

view of one o the Yloose `leaf sheets to be used in the binder. tion, partly in vertical section of a modified form.H Fig-7 is a side elevation of a Sectio similar to that shown in Fig. 6.

In the'illustrative embodiments of my in` 40 vention shown in the drawing lis aloose leaf binder having aback 2, 'cover 3 andv loose leaf pages 4 and an extensible pillar or post'5. As is usual in such binders, the

pillars or posts 5,v only one being shown in\ the drawing, are made in sections 'sogas to be 'extensible to lncrease or decreasefthe lengthof the post and consequently, in-

crease or decrease the capacity of the loose'` leaf binder 1. By my invention I form the pillar 'or post '5 of section 6, 6 having). tongue 7 mounted at one end and a pin 8 ,mounted lat the other 'end of the section, the pin adapted to be seated inia socket 9 a detachable section 6 and the-tongue 7 being adapted to coperate with a screw. thread'lO, preferably of coarse'pitch, a slot 11 being Fig. is a side eleva-v yformed. in the tongue 7 to approximately lit the thread l0. The pitch of thethread y 10 isfpreferablyl so formed that when for instance a pin 8 is placed in th'e socket 9 60 and the screw thread lO'in the slot 11, Fig'. 2, one complete revolutionof one of the secjtions,for .example the upper section, will cause the pin 8 to be seated in the socket 9 and-` securely lock the parts together. l A -Tlie :different sections .6, 6 'are made of suilciently small diameter to tit anopening ,l2-jr; thesheets-4. These openings 12 may beY formed sufficiently large to receive the tongue 7, or in some cases these tongues may: 7 0 be permitted to lie between the walls`13, 13 of the-liling'slotMc in the sheets 4,-F-i'g. 5. In' 'sotneainstancea I may use a support -or disk l5, Figs. 3 and' 4. These supports form anlintegral portion of the pillarv or'post' and'75 serve to` support the loose leaves at intervals -throughout. the binder, it .being understood that one or a plurality of such supports 15 may be used. By using my supports 15, the unnecessary labor of threading a great 80 number of sheets-4 .oand oli thevpillars 5 is avoided when anew leaf is to be inserted vin the binder oran old one removed. When -the pillar 5jis equipped with these supports or disks 15, the position 'in the binder is85 determined where itis desired. to insert or removeva sheet and the ltwo sections 6, 6 nearest this point in the-binder, are disconnected -by rotating one section upon the other. The support or disk? 15 which hap' 90 pens to be' immediately above the section 16 of the post 5 Vwhichis disconnected, will v support the loose leaves or sheets and per- 'fmit their ready removal temporarily with 4the cover 2 until a new ysheet 1s added orang 95 old' one removed. To assist in determining approximately where the pillars. 5 should be disconnected, I may place index numerals or letters upon 'the supports -15. I have shown in Fig..3 for instance the letters AA which may correspond with those uponthe front `index' (not shown), one support or disk being used for e'ach letter of the index,

or for any multiple thereof. These supports or l disks have a substantially cylindrical 105 portion 16, a pin 17 `similar to the pins 8 of the sections 6, a socket 18 for the reception of a" pin 8, and are provided also'with a tongue l19 having a ,slot 20 to'coperatej with a screw thread 10, .a similar screw 110 thread 21 being developed upon the exterior surface ofthe cylindrical portion 16. TheseK disks are connected to the section 6 in substantially the same manner as the different sections 6, 6 are connected to each other, Fig. .2.

In some instances, I A'may develop the coarse pitch screw thread upon the interior of the sections. For instance-in--Fig. 6, I

may have a section 22 witha reduced porl tion 23 at one end provided with a lug 24.

The other en d of the section may be tapped and rovided with a female screw thread v'25' a apted to coperate with `a lug 210i .ments thereof, to the a com lementary section 22, Fig. 7. In this mod" cation the two sections 22, 22 are connected together by inserting lug 24 in the opening 26 of a complementary section and then giving one of the sections a complete turn causing the lug 24 to travel in the securely together.

-Having thus described this-invention in connection with several illustrative embodii female screw thread'25' and bind the parts not desire'v to be limited, what is claimed as new and whatlit is desired tosecure by Letforth in the* appended' ters Patent isset claims. y
